17.12.43      CROSS

REAL CROSS

Indicate the size (in arcsec) of a cross to be drawn at the map projection center, as a reference marker for relative positions. If 0, no cross is drawn.

If CROSS is non 0 and a script "my_cross.ima" is in the current directory, this script is executed instead of drawing a simple cross. This allows to display for example minor and major axes of inclined disks. A generic example of such a script is available in gag_demo:my_cross.ima
It can be tailored by controlling the variables in the mycross% structure.
